Looking at how long it's taking to reach your "graphical.target", Do this, even though it was written at the time of Ubuntu 18.04. It works, even Ubuntu 20.04 (There are two methods; use one or both):

Method One

Type (in the terminal):

$ sudo sed -e 's/^RESUME=/#RESUME=/g' \
     -i /etc/initramfs-tools/conf.d/resume

After that is finished, type:

$ echo "RESUME=/dev/mapper/ubuntu--YOUR FLAVOR OF UBUNTU (eg. mate)--vg-swap_1" | \
  sudo tee -a /etc/initramfs-tools/conf.d/resume

Recreate initrd and reboot system.

$ sudo update-initramfs -u

After that is finished, type:

$ sudo reboot

The kernel boot time should be faster. Verify by typing:

$ systemd-analyze

You will also be able to use hibernation after this.

Method Two

Navigate to /etc/initramfs-tools/conf.d/

Right click on "resume" and choose "Edit as Administrator". Измените строку:

RESUME = UUID = В зависимости от того, что вы номер (ex - RESUME = UUID = 67b3fe6f-1ec4-413f-8c5a-1136bc7f3270)


RESUME = нет

Теперь откройте терминал и введите:

$ sudo update-initramfs -u

После этого введите:

$ sudo reboot

Время загрузки должно быть быстрее.

Снято с: здесь и здесь .
